I am not partial really, but I have built both kits. We put an All Pro kit on a 91 xcab, front and rear lift, and we put a Marlin on an 88 4runner. I have experience installing both, and I will give an honest and impartial opinion. Marlin's kit was easier to install, and it showed up quicker. The Marlin kit flexes better, and the All Pro kit flexes OK, but the rear was too stiff. The ride quality is better with Marlin, that I know for sure. Both trucks went to Paragon last year and I enjoyed the 4runner much better. I am going to try Sky's kit with mine, just to get the best of all worlds. For a third opinion, check there too.
